SHUTTLE.

Application filed September 14, 1922. Serial No. 588,176.

To all whom it may concern:

Be it known that I, WILFRED J. GLADUE, a citizen of the United States, residing at Woonsocket, in the county of Providence and State of Rhode Island, have invented new and useful Improvements in Shuttles, of which the following is a specification.

This invention relates to certain new and useful improvements in shuttles, and the primary object thereof is to provide a shuttle which has means incorporated therein for catching and arresting slubs or knots occurring in the yarn so that the latter will be broken and imperfect work thereby prevented.

A further object of the invention is to provide a device of this type which is adjustable as to the gage or diameter of the yarn, and which may also be adjusted from the outside of the shuttle and more particularly from one of the sides of the latter.

The invention further aims to provide a device of this type which is of simple and economical construction; which can be easily and quickly operated or adjusted and whic involves a minimum of parts assembled adjacent to the throat of the shuttle.

In the drawings Figure 1 is a top plan view of the forward end of a shuttle, parts being broken away and in section, showing the present invention applied thereto;

Figure 2 is a fragmentary side elevation of Figure 1;

Figure 3 is a detail perspective view of the invention.

In proceeding in accordance with the present invention, the shuttle body 1 has the usual bobbin cavity 2 and threading slot 3. A substantially L-shaped plate 4: has its base end 5 secured, for instance by a screw 6, to the bottom of the throat. 7, of the shuttle. The upstanding end 8 of the plate 4: is cutaway on one side to receive the upstanding end 9 of a pivoted L-shaped member 10. The base end 11 of the member 10 is pivoted at 12 to the upper face of the base end 5 of the member 4. The confronting adjacent vertical edges of the upstanding ends 8 and 9 of the fixed and pivoted members 4 and 10, conjointly form a yarn or thread passage 13, through which the yarn passes from the bobbin, and through throat 7. The passage 13 formed conjointly by the members 4: and

10 is in register with the threading slot 3 of the shuttle.

For the purpose of effecting adjustment of the width of the thread passage 13, to provide for thread or yarn of varying gage or diameter, the end 9 of member 10 is provided with a right angular outwardly ex'- tending arm 15, formed with an approximately T-shaped opening 16 which rotatably receives therein, the circular head and shank 17 carried by a screw 18. The screw 18 is threaded into a socket provided therefor in a side of the shuttle and is located slightly above the transverse center of the shuttle.

From the foregoing it will be seen that the thread passes from the bobbin, through the throat 7 and through the passage 13 formed between the ends 8 and 9 of the members 4 and 10, and thence through slot 3 of the shuttle to the delivery eye. If a slub or knot is possessed by the thread, same will be engaged by the ends 8 and 9 and the thread will thus be broken, so that the operator can piece up the yarn and thus avoid imperfections in the finished goods. The adjustment of the passage 13 is easily and quickly effected by mere turning of the screw 18 to effect pivotal movement of the member 10 and its end 9 relative to end 8 of member 4:.

Having thus described my invention, what I claim as new and desire to secure by Letters Patent is 1. In combination with a shuttle having a throat and a thread slot, an L-shaped member having one end aifixed to the shuttle in the throat thereof and having a side of its upstanding end cutaway, a second L-shaped member pivotally secured at one end on top of the base end of the first member and having its upstanding end cooperating with the upstanding end of the first member to form a thread passage, an arm extending outwardly from the outer side of the upstanding end of the second member and formed with a T-shaped opening, and a screw turnably carried by a side of the shuttle and having a circular head and shank rotatably engaged in the T-shaped opening.

2. In combination with a shuttle having a thread slot extending from the throat of the shuttle, a pair of relatively movable thread engaging members carried by the shuttle and arranged between the slot and throat, a screw carried by the shuttle and operable from the outer side face of the shuttle, and means between the screw and one of said members whereby rotation of the screw efiects relative movement between the two members.

3. In combination with a shutt1e,,a pair of relatively movable members carried by the shuttle and having parts forming a thread passage therebetween, and means to adjust said members to vary the size of the thread passage.

4. In combination with a shuttle, a member fixed therein and having a thread engaging part, a second pivoted member having a thread engaging part cooperating with said part of the first member, and means operable from anouter side face of the shuttle for adjusting the pivoted member.

In testimony, whereof I have signed my name to this specification in the presence of 20 two subscribing witnesses.
